[R-sig-eco] envfit permutation significance

[jsgro]

I have fitted a vector (a variable) using envfit to an RDA of sites, species,
and environmental variables. The envfit permutation (999 permutations) was
not significant, but envfit placed the vector on the RDA plot. How exactly
do I interpret this plot? Is the placement of the vector meaningless (just
random) because the permutation result was not significant? or does the
vector placement have meaning, but it just cannot be predicted from the RDA
with confidence?
